mimicing .. hmm, seems that can be a fem trait occasionally - on another note how does this 'cupping' enhance the effect? (personally the fist-thumping appeals as a tympanic device w/ accompanying Tarzan-like vocals)

The cupping makes the noise a big bigger. Kinda like echo. If you thump, you are relying on your chest cavity to rebound any noise while cupping makes it more exterior. I think.

It is also less painful for a similar amount of noise. The technique in no way hinders the Tarzan-like vocals._________________Before God created Las he pondered on all the aspects a woman might have, he considered which ones would look good super-inflated and which ones to leave alone.

Hehe! This one reminds me of my friend who once illustrater me how a male gorilla doesn't actually hit its chest with its fists but with its hand shaped like cups.
...how can somebody know something like that? ...well he's Lauri.

Did you know that of apes (humans included), gorillas have the smallest penis to body size ratio, maybe they're just compensating. (Chimps have the largest btw)_________________...if a single leaf holds the eye, it will be as if the remaining leaves were not there.http://about.me/omardrake
